Display Relais switches ** Possible cause Reaction of ControllerSymbol Operation Failure AdjustmentEarth fault1 1 Short-circuit at motor connection toearthThe device switches off, restarts afterapprox. 60 s.Final switch-off after three successive at-tempts (resp. < 60 s).Check motor connection cable.Reset by disconnecting the line voltage.IGBT Temp.1 1 Temperature of the heat sink toohighThe device switches off and switchesback on when the temperature drops.Check cooling of the device (IGBT tem-perature Diagnostics menu).IGBT Fault1 1Overload shutoffShort-circuit between the motorlinesThe device switches off, restarts afterapprox. 60 s.Final switch-off after three successive at-tempts (resp. < 60 s).Check motor connection cable.Reset by disconnecting the line voltage.Sinefilter1 1Sine filter temperature too high(only in version with integrated sinefilter)The device switches off and switchesback on when the temperature drops.Check cooling of the device (sine filterDiagnostics menu).Overload 21 1The device was operated for toolong with too high current (> ratedcurrent).The device switches off, restart after ap-prox. 30 s. Final switch-off after 5 suc-cessive attempts (resp. < 10 min), thenreset necessary.Check high output current.DC over voltage0 1 To high DC-link voltageImmediate switch-off, the error is dis-played after 75 s.When voltage okay again, restart after 15s.Check line voltage.AC undervoltage0 1 Line voltage too highError is displayed after 75 s.When voltage okay again, restart after 15s.Check line voltage.AC undervoltage0 1 Line voltage too lowError is displayed after 75 s.When voltage okay again, restart after 15s.Check line voltage.DC over voltage0 1 Intermediate circuit voltage too lowError is displayed after 75 s.When voltage okay again, restart after 15s.Check line voltage.Peak current1 1 Current above defined limitThe device switches off, restart after ap-prox. 30 s. Final switch-off after 10 suc-cessive attempts (resp. < 90 s), thenreset necessary.Check high output current.Filterchoke1 1 Input choke temperature too highThe device switches off and switchesback on when the temperature drops.Check cooling of the device (filter choketemperature Diagnostics menu).Elcap. Temp.1 1 Temperature of the electrolytic ca-pacitors too highThe device switches off and switchesback on when the temperature drops.Check cooling of the device (electr. ca-pacitor temperature Diagnosticsmenu).External error0 selectable Alarm from external contact Device continues working unchanged.check contacts.Operating Instructions Fcontrol – model series FXDM25/32AM ProtocolL-BAL-E212-GB 1451 Index 003 Part.-No.116/123
